Find the value of $3x+5$ and $6+8x$ when $x=3$ .

STEP 1

Assumptions
1. The value of $x$ is given as 3.
2. We need to evaluate two expressions, $3x+5$ and $6+8x$ , by substituting $x$ with 3.

STEP 2

Evaluate the first expression $3x+5$ by substituting $x$ with 3.
$3x+5 = 3(3)+5$

STEP 3

Perform the multiplication in the expression.
$3(3)+5 = 9+5$

STEP 4

Add the numbers to find the value of the first expression.
$9+5 = 14$
The value of the expression $3x+5$ when $x=3$ is 14.

STEP 5

Evaluate the second expression $6+8x$ by substituting $x$ with 3.
$6+8x = 6+8(3)$

STEP 6

Perform the multiplication in the expression.
$6+8(3) = 6+24$

STEP 7

Add the numbers to find the value of the second expression.
$6+24 = 30$
The value of the expression $6+8x$ when $x=3$ is 30.
The solutions are: a) $3x+5 = 14$ b) $6+8x = 30$
